@MattPRD @Muse Hi

[Simon Chemouil @simach]

@MOREFIGURES_ @coinbase @krakenfx Welcome! We know people like to see their portfolio going up 🌒, so we did some work earlier this year to make sure we can display balances even when most things break. Always doing work so they don't break though 🙃

@jroper @TracketPacer She's talking of the latency inside the aircraft.

Another sign of the looming Armageddon 🙏

I’m going to share with you all something I shared with someone on an advisory call this week:

Stop rewarding the academic theater of PM best practices.

I’m tired of folks thinking you put insights into a magical PM framework and a great business spits out the other end.

@sheevink Ridiculous and childish.

@fulmicoton I'd say avg O(n) which is also the lower bound when reading n random integers so O(k) cannot be the larger term if n > k. Sounds like an online version of quickselect (itself avg O(n)), where windowing can be used to amortize to O(n) on avg.

This Week in Rust: outraged @rustlang community armed with pitchforks led by ex-members with personal vendettas and YouTube ad dollars, using any opportunity to demonize project leadership while claiming moral high ground. Disgraceful.

At the time I also ran all technical interviews for the Engineering department at that startup but game performance was a better predictor than any interview exercise. Other top performers noticed and I used to joke that we should replace the interview process with a few games.

[Simon Chemouil @simach]

Reminds me how we'd notice at work LAN parties how the game behavior matched work practice (slow & steady performers, struggling to learn, etc). We'd have interns and new hires join and it would very often match their future performance and working style.

[Crémieux @cremieuxrecueil]

The "g" in "general intelligence" stands for "gamer".

You can measure general intelligence extremely well using video game performance. The correlation in a model that underestimates? 0.93.

@lufthansa I did, multiple times. Same reply everytime where Customer support seems to ignore the compensation offer of April 6th. Is this time going to be any different?

[Simon Chemouil @simach]

.@lufthansa after a serious mess from your end leading to 2000€ extra cost for me, your consumer support offered on April 6th 1424€ of compensation. I asked about the 600€ difference and since then have been ghosted by your services to get the proposed 1424€. Please address.

@houlihan_rick @mikbarbero I've used both Java and Rust extensively and the mental tax is far, far higher in Java. You need to keep up with side effects, data races, inheritance limitations, exceptions, a lot of bad APIs and then you have to tune the JVM. The Rust compiler handles that cognitive load.

[Vanius Bittencourt @vaniusrb]

This type of statement is very common in the Rust community. Often in large refactorings when it compiles it just works. #rustlang

[Simon Chemouil @simach]

@jespow Joke aside, this is how memory allocation algorithms work (it's a classic CS problem), and that is where Amazon Engineers got the idea and "reinvented" warehouse storage against conventional wisdom. Culture needs to be adequate to empower engineering to build and invent.

[Simon Chemouil @simach]

It goes against common wisdom, but sometimes it is the right thing to do. We look back on the decision with no regrets but a great feeling of accomplishment. I will soon blog an update on @rustlang at @krakenfx to shed more light. 🦀⚙️🐙

There are few projects more humbling than a multi-year migration. Eg breaking a monolith using one language to smaller services using another language/framework.

These are both thankless projects, challenging, and risky if not done properly.

And it rarely starts as multi-year…
